Installation and Maintenance Guide: Before You Begin 4
Before You Begin
With the Cardio Theater®xTV wireless system, fitness facilities can
add entertainment to exercise rooms without the high cabling costs
usually associated with entertainment systems. The xTV wireless
system gives people the choice of listening to music, radio, or
programs shown on TVs while they exercise. The person simply
plugs a stereo headphone into a receiver, selects the desired
entertainment, and exercises while listening to high-fidelity sound.
An xTV wireless system consists of one multi-channel xTV-9TM
Transmitter and a number of xTV900 Receivers installed on exercise
equipment throughout the room. The xTV-9TM Transmitter may
contain up to 12 channel cards, allowing facilities to connect up to
12 components to support a wide variety of entertainment options.
Preconfigured programming modes allow facilities to assign each
component its own frequency to ensure clear transmission while
avoiding any frequencies that may already be used in the area.
This guide explains how to install and maintain an xTV-9TM
Transmitter. For proper installation, please read this guide thoroughly
and follow the instructions.
Note: For information about the xTV900 Receivers, refer to the
xTV900 Receivers Installation and Maintenance Guide.
Obtaining Service
Do not attempt to service the xTV-9TM Transmitter except as
described in this guide. For information about product operation or
service, contact an authorized Cardio Theater Technical Support
Representative at 1-800-776-6695 or [e-mail].
Representatives are available to serve you from 6:00 to 5:00 pm,
Monday through Friday, U.S.A. Pacific Time.
Returning Equipment to Cardio Theater
To return equipment to Cardio Theater for any reason, you must
contact Cardio Theater Technical Support and obtain a Return
Authorization Number (RMA). When requesting the RMA number,
explain why you are returning the equipment, for example you
ordered too many receivers and the extra receiver can be returned to
stock, or the equipment needs repairs.
Important: Equipment must be shipped with an RMA number in
order for Cardio Theater to process it. Any equipment received
without an RMA number will be returned to the sender.

Installation Requirements
Review the following requirements before installation:
• To ensure the best range and audio quality, select a location
without any major internal obstructions, such as metal support
posts, between the transmitter’s antenna and receivers installed
on the exercise equipment. The antenna and receivers should also
be installed so they are within 150 feet (50 meters) of each other
and are in direct line of sight.
• Cardio Theater recommends that you group audio components
together to minimize cabling. You can install the transmitter in a
rack with other audio components if desired.
• If the audio components are stacked in a cabinet, make sure the
equipment has adequate ventilation to avoid overheating.
• Install the antenna nearby so it is vertical. Do not install the
antenna so it is mounted horizontally, which will decrease its
transmission range. In addition, the antenna should not touch or
come near other transmitting antennas or metal objects. Be sure
to route cabling and power cords away from the antenna, so they
do not cause interference.
• You can mount the antenna up to 25 feet (8 meters) from the
transmitter. A coax cable (RG-58 or RG-8) connects the antenna
to the transmitter and eliminates any interference issues between
these two components. Using a higher quality (lower loss) cable
will allow a greater distance between the transmitter and antenna.
• Each audio component connected to the transmitter requires a
unique channel number. Channel numbers on a transmitter
determine frequencies. There is no correlation between channel
numbers on a transmitter and channel numbers shown on
receivers when they are programmed.
• The xTV-9TM has four programming modes to support different
situations and countries. Each mode has different frequencies
assigned to its channels. Refer to the following tables to identify
the mode appropriate for your installation.

• If you discover that some of the 900 MHz frequencies (see
Tables 1–4) are used by outside non-controllable sources, you
can set the transmitter to avoid those frequencies. However, this
will reduce the number of channels available for you to use when
installing transmitters. If the outside non-controllable source
generates a powerful signal, it may also cause static interference
with the wireless system, reducing audio quality.

Installation and Maintenance Guide: Preparations 8
• The transmitter uses Automatic Level Control (ALC) circuitry to
provide consistent sound levels to people using the receivers.
With this feature, once the sound level on TVs and other audio
components have been adjusted, the wireless system should not
experience sound fluctuations, which have been inherent in other
types of entertainment systems. To support this feature, the sound
level from the connected TV and audio components must be set to
a reasonable, median level. If the incoming sound level is set too
low, people may hear an excessive amount of background noise
while using the receivers. If the incoming sound level is set too
high, it may sound distorted through the receivers.
• To avoid confusion with people using the wireless system, you
want receivers to logically select TV and audio components based
on their placement. So, on the receiver, channel 1 would select the
first TV, channel 2 would select the second TV, and so on. To
support this logical usage, connect components to the transmitter
in channel order. The following explains how receivers assign
channels numerically.
The receiver automatically searches the area for active transmitter
channels and stores them in memory. It then assigns them to
channel numbers, starting with the lowest transmitting channel to
the highest transmitting channel, regardless of which channels are
used. For example, an installation has an xTV-9TM Transmitter with
assigned channel numbers 2, 4, 6, and 8; they are installed in that
order from left to right. The receiver has found these transmitted
channels and assigned them to a sequence of channel numbers
that it displays as 1 through 4. See Table 5.

Installation and Maintenance Guide: Installing the Transmitter 9
Installing the Transmitter
1. Determine where you will install the transmitter and antenna.
An RG-58 or RG-8 coax cable connects the antenna to the
transmitter.
You can mount the antenna up to 25 feet (8 meters) from the
transmitter: using a higher quality (lower loss) cable will allow a
greater distance between the antenna and transmitter.
If possible, locate the antenna where its signals will have no
obstructions (such as metal support posts) to the receivers
installed on the exercise equipment. In addition, the distance
between receivers and antenna should not exceed 150 feet
(50 meters).
2. Place the transmitter where it will operate. Make sure that it is
located in a well-ventilated area with both the front and back
easily accessible. You can set the transmitter on a shelf or install
it in a rack with other components.
3. Install the antenna assembly in a vertical configuration. Typically,
the antenna assembly is installed on a wall near the transmitter.
The fastening hardware needed to install the assembly depends
on the wall, and must be provided by the installer.
Be sure to mount the antenna assembly away from sources that
will cause static interference, such as cables, other antennae,
and metal objects.
4. Once the antenna assembly is mounted to the wall, adjust the
orientation of the antenna so it points toward the receivers. The
bracket can be rotated 180 degrees. Doing this helps to ensure
better transmission quality to the receivers.
5. After adjusting the orientation of the antenna, secure the bracket
placement by tightening the two screws in the bracket junction
with the Phillips-head screwdriver.
6. Connect the coax cable with the BNC connectors on both ends
to the antenna, and then connect it to the transmitter. Make sure
the placement of the coax cable does not cause a problem for
people or other equipment.
7. Plug the AC power cord, packaged with the transmitter, into the
back of the transmitter.
8. Plug the AC power cord into a nearby power outlet.
9. Clamp the provided ferrite filter onto the antenna coax cable in
close proximity to the transmitter.
